Benefits of technology
The patent describes a mounting device for a linear actuator in a wind turbine. The device includes two wedges that are attached to a frame and a supporting plate of the actuator. This setup ensures good alignment of the actuator with the wind turbine component and provides a secure grip on the frame. The patent also mentions the use of two tools, each containing a linear actuator and a mounting device for it. This arrangement makes it easier to operate the actuator and improves control during lifting operations.
Problems solved by technology
Some of these components, particularly the generator, the gearbox, the rotor and the transformer, are extremely heavy and therefore require the use of a crane for handling.
Bearing in mind the strict limitations regarding maintenance work, given that wind turbines are installed in tall towers and built in, generally, in solitary areas, the use of external cranes leads to problems of availability and cost.
When a maintenance work shall be carried out when the wind turbine is de-energized or in commissioning mode, internal cranes needing an electric supply cannot be used so that there is a need of lifting tools that can operate in these situations for performing a variety of maintenance works.

Embodiment Construction
[0035]FIG. 1 shows the nacelle 11 of a wind turbine that houses a gearbox 21 and a generator 23 driven by a shaft coupled to a rotor hub 25 and a transformer 27 supported by the nacelle frame 29. The nacelle frame 29 also includes a supporting structure of a gantry crane 31 formed by vertical and horizontal I-shaped beams 33, 35 which is used for performing mounting / dismounting operations of wind turbine components. The roof 37 of the nacelle 11 is shown in an open position.
[0036]FIGS. 2a and 2b show an apparatus comprising a tool 40 that can be used temporarily for supporting and / or lifting a wind turbine component installed in an I-shaped beam 35 belonging to the nacelle frame 29. The tool 40 comprises a manually operated linear actuator 41 with an attachment arm 43 and a mounting device 61 configured for mounting said linear actuator 41 in said I-shaped beam 35.
[0037]The tool 40 can be used as a temporary support means of a wind turbine component attached to it by means of the at...

Abstract
An apparatus for performing a supporting and / or a lifting operation to a wind turbine component inside the wind turbine nacelle is provided. The apparatus comprises at least a tool which comprises a manually operated linear actuator and a mounting device of said linear actuator in an element of the nacelle frame so that said linear actuator can be duly located with respect to the wind turbine component for performing said supporting and / or lifting operation.
Description
BACKGROUND OF THE INVENTION[0001]The present invention relates generally to lifting tools for wind turbines and more particularly to manual lifting tools.[0002]Wind turbines are devices that convert mechanical energy to electrical energy. A typical wind turbine includes a nacelle mounted on a tower housing a drive train for transmitting the rotation of a wind rotor to an electric generator and other components such as a yaw drive which rotates the wind turbine, several controllers and a brake. The wind rotor comprises a rotor hub supporting a number of blades extending radially therefore capturing the kinetic energy of the wind and causing the drive-train rotational motion.[0003]Wind turbines are designed to ensure that their main components have a long working life, which means that regular maintenance work on the parts subject to greatest wear shall be carried out. Some of these components, particularly the generator, the gearbox, the rotor and the transformer, are extremely heavy...
